Considerazioni in merito all’uso dei test mentali nella quantificazione del danno biologico di natura psichica

Gli autori, pur rimarcando la centralità del colloquio strutturato e dell’esame delle condizioni mentali per la valutazione del danno biologico di natura psichica, sottolineano altresì l’importanza, all’interno di un corretto esame psicodiagnostico, dei test mentali quale utile supporto per la quantificazione del danno stesso, a condizione di conoscerne peculiarità e limiti

Left ventricular midwall mechanics at 24 weeks' gestation in high-risk normotensive pregnant women: Relationship to placenta-related complications of pregnancy

Most studies during pregnancy have assessed maternal left ventricular (LV) function by load-dependent indices, assessing only chamber function. The aim of this study was to assess afterload-adjusted LV myocardial and chamber systolic function at 24 weeks' gestation and 6 months postpartum in high-risk normotensive pregnant women

Spatio-temporal variability of Borer Polychaetes in Posidonia oceanica beds and its relation to meadow structure

Posidonia oceanica forms an extremely productive and complex ecosystem in the coastal Mediterranean Sea providing a suitable habitat for hundreds of plant and animal species. Among motile invertebrates associated to Posidonia meadows, polychaete borers of the plant sheaths represent a unique group which exploit a peculiar microhabitat. They belong to the family Eunicidae with three dominant species, Lysidice collaris, L. ninetta and L. unicornis. Due to their strong association with Posidonia shoots, these animals are particularly suitable to study the plant and animal spatial relationships and their pattern of variability. The aim of this work was to evaluate the frequency of occurrence of these animals (Index of Borer, IB) at different spatial and temporal (summer vs winter) scales in two Posidonia meadows off the Ischia Island (Gulf of Naples, Italy), which are exposed to different degrees of human impact and of hydrological conditions. Results showed IB values of L. collaris (the most abundant species) significantly different between meadows and at scales from 10s to 100s of meters, as well as between summer and winter. The IB of L. ninetta showed significant differences only at scales of 10s of meters while, on the contrary, the IB of L. unicornis (the less abundant species) did not show variability at any spatial and temporal scales. Most of the variance was at the more impacted and less water movement exposed meadow, suggesting higher level of small and intermediate scales of patchiness of borers at this meadow. These variation patterns are discussed in relation to local environmental differences between the studied Posidonia beds

El fundamento de la política del vivir bien: la economía política de los trabajadores y las trabajadoras como alternativa

Las opciones de políticas públicas frente a la crisis derivan estructuralmente de la dominación del capital –como relación social– sobre la sociedad. La base de esas políticas es la economía neoclásica, la economía política del capital. Los Estados capitalistas remiten a las necesidades de reproducción de esa relación a la hora de plantear opciones frente a los límites sociales del capital. Esto no significa, sin embargo, que no haya alternativas. Contrariamente, la práctica de organización y lucha social de los movimientos populares en América del Sur muestran los trazos del fundamento de una nueva economía política. Esa economía política (de las trabajadoras y los trabajadores) se funda en principios diametralmente opuestos a la economía política neoclásica o del capital. Esos principios alumbran en la actualidad la posibilidad de pensar e impulsar una nueva estrategia de desarrollo social y económico: la política del vivir bien. Rastrear esos principios y fundamentos de las alternativas populares frente a la crisis de la sociedad dominada por el capital es el objetivo de este trabajo.Facultad de Humanidades y Ciencias de la Educació

An overview of bottom trawl selectivity in the Mediterranean Sea

In the Mediterranean Sea, where bottom trawling for demersal species is the most important fishery in terms of landings, around 75% of the assessed fish stocks are overfished. Its status as one of the world’s most heavily exploited seas and the one subject to the highest trawling pressure has become a global concern. An extensive overview of bottom trawl selectivity studies was performed to assess the sustainability of this fishery in the Mediterranean. The selectivity parameters were collected from 93 peer-reviewed publications from 10 countries, totalling 742 records and 65 species. Our review highlighted that i) the catch of the bottom trawls commonly employed in the Mediterranean, although they comply with current codend mesh regulations, still includes immature individuals of 64-68% of the species investigated, and individuals under the minimum conservation reference size (MCRS) of 78% of the species investigated, and that ii) the MCRS set for 59% of the species analysed is well below their length at first maturity and is therefore ecologically inadequate. Although square-mesh codends are slightly more selective, the models developed herein demonstrate that improving size and species selectivity would require considerably larger meshes, which may significantly reduce profitability. The urgent need to mitigate the biological impacts of bottom trawling in the Mediterranean should be addressed by promoting the adoption of more ecologically sustainable fishing gears through the introduction of more selective meshes or of gear modifications

Photoreduction of Carbon Dioxide to Formic Acid in Aqueous Suspension: A Comparison between Phthalocyanine/TiO2 and Porphyrin/TiO2 Catalysed Processes

Composite materials prepared by loading polycrystalline TiO2 powders with lipophilic highly branched Cu(II)- and metal-free phthalocyanines or porphyrins, which have been used in the past as photocatalysts for photodegradative processes, have been successfully tested for the efficient photoreduction of carbon dioxide in aqueous suspension affording significant amounts of formic acid. The results indicated that the presence of the sensitizers is beneficial for the photoactivity, confirming the important role of Cu(II) co-ordinated in the middle of the macrocycles. A comparison between Cu(II) phthalocyanines and Cu(II) porphyrins indicated that the Cu(II)- phthalocyanine sensitizer was more efficient in the photoreduction of CO2 to formic acid, probably due to its favorable reduction potential

Generation of ribosome imprinted polymers for sensitive detection of translational responses

Whilst the profiling of the transcriptome and proteome even of single-cells becomes feasible, the analysis of the translatome, which refers to all messenger RNAs (mRNAs) engaged with ribosomes for protein synthesis, is still an elaborate procedure requiring millions of cells. Herein, we report the generation and use of “smart materials”, namely molecularly imprinted polymers (MIPs) to facilitate the isolation of ribosomes and translated mRNAs from merely 1,000 cells. In particular, we show that a hydrogel-based ribosome imprinted polymer could recover ribosomes and associated mRNAs from human, simian and mice cellular extracts, but did not selectively enrich yeast ribosomes, thereby demonstrating selectivity. Furthermore, ribosome imprinted polymers enabled the sensitive measurement of an mRNA translational regulatory event, requiring 1,000-fold less cells than current methodologies. These results provide first evidence for the suitability of MIPs to selectively recover ribonucleoprotein complexes such as ribosomes, founding a novel means for sensitive detection of gene regulation

Intertidal mediterranean coralline algae habitat is expecting a shift toward a reduced growth and a simplified associated fauna under climate change

none13Coralline algae represent the most important bioconstructors in the Mediterranean Sea and are currently impaired by the effects of climate change (CC), particularly by global warming and ocean acidification (OA). We studied the effects of these two drivers on Ellisolandia elongata, an intertidal coralline algae that is known to host a rich biodiversity of associated fauna. We cultured turfs of E. elongata in experimental conditions of increased temperature and OA (using the values of the IPCC scenario RCP- 8.5 expected for 2100: actual mean temperature +3°C and pH = 7.78), and estimated alteration of algal linear growth and community structure, focusing especially on peracarid crustaceans and annelids. Our findings revealed a decrease in linear growth, yet with no significant changes on structural integrity, and a simplification of associated community, in particular for peracarids. Our study contributes to understand community-level response to CC drivers, highlighting the vulnerability of the fauna associated to an important Mediterranean marine habitat.openMarchini A.; Ragazzola F.; Vasapollo C.; Castelli A.; Cerrati G.; Gazzola F.; Jiang C.; Langeneck J.; Manauzzi M.C.; Musco L.; Nannini M.; Zekonyte J.; Lombardi C.Marchini, A.; Ragazzola, F.; Vasapollo, C.; Castelli, A.; Cerrati, G.; Gazzola, F.; Jiang, C.; Langeneck, J.; Manauzzi, M.
